Fraction Circles (Nienhuis)
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Circles divided into equal parts, from the whole down through the family of fractions, in frames a child can lift the pieces out of. The material carries far more than naming: correct terminology first, then equivalency, then the four operations with fractions, then conversion to decimals, and eventually measurement of angles, because a circle divided into parts is also a protractor waiting to be noticed. Few materials stretch that far, which is why this one stays on the shelf for years. Wood with a painted finish, for ages 6 to 12.
“The hands are the instruments of man's intelligence.”
The Fraction Circles emerge in the mathematics area when children demonstrate readiness to explore part-whole relationships beyond simple counting.
- Understanding that wholes can be divided into equal parts
- Recognizing fractional parts as divisions of a single unit
- Comparing sizes of different fractional pieces visually and manually
- Building vocabulary for fractions (half, third, quarter, etc.)

Each red circle, precisely divided by white lines on its green wooden board, transforms the abstract concept of fractions into a tangible experience children can touch and manipulate. The progression from whole circles to circles divided into halves, thirds, quarters, and smaller parts mirrors the child's growing capacity to understand division as equal sharing. The visual contrast between the red circles and white division lines creates clear boundaries that help young minds perceive how one whole can become many equal parts. This material bridges the gap between the child's concrete operational thinking and the eventual abstraction of fractional notation, allowing mathematical understanding to develop through repeated sensorial exploration rather than memorization.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the Fraction Circles tray on a table mat. Arrange the boards in order from whole to smallest divisions. Have a soft cloth ready for handling the circles.
- 1
Begin with the whole circle, tracing its edge with two fingers while saying 'This is one whole circle'
Move slowly and deliberately to emphasize the complete form - 2
Move to the circle divided into halves, trace each half separately saying 'This is one half' for each piece
Pause between tracing each piece to emphasize they are separate parts - 3
Remove one half and place it beside the board, then replace it, noting how two halves make one whole
Use both hands symmetrically when handling pieces - 4
Continue with thirds, removing one piece at a time and counting how many pieces make the whole
Let the child discover the pattern of increasing numbers - 5
After exploring each circle separately, compare pieces from different circles by placing them side by side
Start comparisons with dramatically different sizes like halves and eighths
